Definitions

  • British Patent 780,974 discloses a process of producing uranium billets by reducing uranium tetrafluoride with magnesium. The billets are subsequently vacuum cast into moulds to produce bars of uranium and the bars are machined to size, and enclosed in protective sheaths to make fuel elements.
  • the invention accordingly resides in the treatment of uranium metal to bring the iron and aluminium contents into the range of 200 to 500 p.p.m. and 500 to 1200 p.p.m. respectively.
  • Two dotted lines 4 and 5 are shown which indicate boundaries of zero refinement, and partial refinement.
  • the area between line 5 and boundaries 1, 2 and 3 is an area in which suitable grain refinement can be usefully carried out and the box 6 defined by lines 3, 5, 7 and 8 shows the area of reasonable process limits within the area of refinement.
  • uranium bars made as described above will have a peripheral grain structure refined by a factor of 6 to 30 from the largest initial grain size of about 2.0 to
  • the peripheral grain refinement region should extend inwards to a depth of about 6 mm. towards a core which may be less refined than the periphery.
  • the quenching of the uranium bar has been stated above to take place at 720 C. This is the preferred temperature but other temperatures could be employed, the criterion being that the quenching should take place from a temperature not lower than that at which the iron and aluminium go into solution in the uranium. Similarly the annealing can take place in a range of temperatures 500 C. to 600 C. and over a range of times of one hour to 48 hours.
  • An alloy essentially containing uranium, two hundred to five hundred parts per million of iron, and five hundred to twelve hundred parts per million of aluminum.
  • a process comprising making an article from the alloy of claim 1, such article having its initial largest peripheral grainsize inthe range from two to three mil-limeters, beta quenching and then alpha annealing said article to refine the peripheral grain size by a factor of six to thirty from said largest initial peripheral grain size.
